Specific embodiment

As shown in Figures 1 to 6, the utility model proposes a kind of eccentric Knife handle structure that floats, including handle of a knife 1 and for pacifying The joint 2 of dress cutter；The linkage section 12 that the handle of a knife 1 includes construction section 11 and matches with machine tool chief axis, the construction section 11 sets There is the installation passage 3 for installing the joint 2, and there is gap, institute between the construction section 11 and the joint 2 when installing Stating joint can carry out radial floating in the installation passage 3, and the both sides of the installation passage 3 are provided with axially symmetric insertion groove 111, the end face of one end insertion to the construction section 11 of the insertion groove 111, the other end is provided with the caulking groove 112 of radial direction, institute State the side that caulking groove 112 is respectively positioned on the insertion groove 111；The construction section 11 is provided with a telescopic thrust screw 41, and The thrust screw 41 is located on the side wall of the bottom of the installation passage 3, and at least three are provided with the installing port of the construction section 11 Individual telescopic floating screw 42, the floating screw 42 is uniformly distributed along the outer radial of construction section 11, and the floating spiral shell The distance that the free end of silk 42 inserts the construction section 11 is equal.According to three points one concyclic principles, floating screw 42 makes joint 2 When floating with cutter radial, its can the power of oriented center fine setting all the time maintain cutter to carry out Rule Activity, it is ensured that cutter with treat The alignment of processing workpiece centre.

Further, as shown in Figure 1 and Figure 4, in the present embodiment, the head of the joint 2 is provided with a pair and can pass through Insertion groove 111 is embedded in the alignment pin 21 of the caulking groove 112；The joint 2 is that the Morse's taper with tang is constructed, the joint 2 are provided with removal hole 22 at tang, and the removal hole 22 easily can unload cutter from joint 2 under the insertion of cone block. The end face of the head of the joint 2 is provided with an arc-shaped slot 23 so as to can preferably be fitted in the side of shown thrust screw 41.Institute The centrage and the central shaft of the alignment pin 21 for stating arc-shaped slot 23 has one first radial direction angle γ, and described first radially presss from both sides Angle γ is 25 °；The centrage of the end face of the insertion groove 111 has one second radial direction angle ω with the end face of the thrust screw 41, And the second radial direction angle ω is 25 °.Further, the installation direction when inlay card of the joint 2 is in the grinding handle of a knife 1 Direction of rotation when working with milling cutter is contrary, it is ensured that be not in joint when grinding handle of a knife 1 works with milling cutter 2 situations about releasing from grinding handle of a knife 1.
